Fig. 7 is a section along the line 7 7' in Fig. 6, looking' in the direction of the arrows, the roller being shown in the position which it assumes while traversing a curved portion ot the track with the weathering plates assuming an accommodating position therefor.

Fig. 8 is an end view of the door while in the position shown in Fig. 7, the door being viewed in the direction of the arrow 8 in said last ligure.

Referring to Figs. 1 and 5, the numeral 10 designates a door which may be formed by a plurality of vertical standards 11h11, spaced from each other and of which only two are shown in said ligures. These sta-ndards are preferably oit tubular construction and the two which are shown in Figs. 1 and 5 are spaced apart by a brace 12 which is disposed a. predetermined distance above the lower edge of the door to torni a recess 13. The outer and inner faces oli the standards 11 have attached thereto cover plates 14 and 15, which are 'lined in position and cover the entire sur-tace of the door except the recess 13 which is enclosed by plates hereinafter described. The recess 13 is utilized to receive a supporting roller for the door .vhich moves along a suitable trackway, all oit these parts being described hereinafter, and will further be understoodthat the end of an airplane hangar is enclosed by a. plurality of the doors 10, as described more :tullyin my co-pending application, Serial No. 373,863. filed July 17, 1929.

Located within the upper end ol the recess 13 is a .trame 16 having oppositely eX- tending arms 17 which seat against the o posed inner faces ot the standards 11, 11 and are secured thereto by means of bolts 13 and 19 (see Fig. The trame 16 is employ/fed as a means of roller support and to that end, a spindle 2O is journaled in a bearing 21 formed in the lower portion oli said frame and said spindle threadedly receives vthe lower end ot a stem 22 whose upper end is journaled in a bearing 23 provided in the upper end of the trame 16. The stem 22 is provided with an enlarged, wrench-receiving head 24, by means of which the vertical, position of the spindle 20, and accordingly the supporting roller as hereinafter described, may be adjustedv to maintain the door 10 a predetermined distance above the ground and the adjustment so made may be locked by a nut 25. However, the vertical adjustment oil the spindle 2O forms no part ot the present invention and other devices for achieving the same result may be adopted desired. The lower end of the spindle 2O has provided thereon a saddle 26 having a pair of spaced, depending, side members 27 through which extends transversely an axle for a supporting roller 29. Said roller is preferably of a dual iianged type and normally runs upon a track 30, whereby the door 1() may be moved from position to position as desired.

In order to adequately house the supporting roller 29 and to prevent the passage of wind and rain through the recess 13 into the interior of the hangar, a pair of weathering plates 31 and 32 are substantially hingedly connected to the door 10 on opposite sides thereof ior the purpose of accommodating the swiveling action of the roller 29 as it traverses the curved portions of the track 30, the plate 31 being secured to the outer face oit the door 10 and the plate 32 to the inner ii'ace thereof. Specilically, and referring to Figs. 5 and 6, the plates 31 and 32 are provided with flat portions 33 and 34, respectively, along their upper edges and said portions normally seat against the opposite side faces oi" the brace 12. A, predetermined distance below said portions, the plates 31 and 32 are slightly ollset therefrom and have attached to their respective inner faces brackets 35 and 36. Fach plate has a pair of said brackets in spaced relation to each other, with the brackets 35 being positioned between the brackets 36, as Vshown clearly in Fig. 2. All of said brackets are secured to t-he indicated weathering plates at substantially the same elevation and to the brackets 35 are pivotally secured one end of pins 3'? which are loosely reciproeable within holes 38 providedy in the trame 16. Similarly, one end of aY pin 39 is pivotally secured to each ofthe brackets 36 and said pins are loosely7 reciprocable within holes 40 also provided in the frame 16. rlhe longitudinal axes of the pins 37 and 39 lie in the same horizontal plane and said pins constitute the soleverti cal support for their respective weathering plates. VBelow said pins, the weathering plates 31 and 32 entend downwardly to co1npletely cover the recess 13, and at their lower edges, the plates may have secured thereto a retaining strip 41 for the purpose of holding a. depending; skirt 42 which may be formed of any suitable flexible material. such as rubber, canvas, and the like, and which depends further from each ot the plates in substantial continuation thereof to a predetermined distance below the head of the track 30, thereby completely closing the opening between the loweredge of the door 10 for the width of each of the weathering plates and the head of said track. A similar retaining strip 43 and skirt 44 may be attached to the remain der of the lower edge of said door, as shown in Fig. 1.

In order to retain the weathering plates 31 and 32 in the normal positions shown in i-,siaiao w Figs, 1 and 6 `and.'torinsure-their .retiirnto said positions Vafter. being displaced; tliereg from as described mere` fully hereinafter:,-,v
